Hey, I've been trying my hand at restoring pipes for a couple months now, and I'm having the same problem repeatedly. When I clean the internals out, I THINK I do everything my research tells me to: I get all the gunk out of the stem and airway, clean it real, real good with rubbing alcohol until pipe cleaners come out clean, even do salt and alcohol treatments. Now, I'm getting into this all on my own, so I don't have anything to compare with, but I would think I should be eventually coming up with a pipe that has no taste, like a new- but I still get a strong scent/taste that reminds me on antique store. Could this just be the natural taste of the briar, or something irreversible that should be eventually covered up through smoking, or am I missing something completely?
